Compressor Filter Holder 3/8"

This is a filter holder for cheap vacuum cleaner cartridges (90mm dia/ 25mm height) that can be found at the Van Cranenbroeck storee in the netherlands. These filters cost about 2€ each and are very well made. They are from the cheap Nevac brand.

I found my compressor came with very bad filters: just a small piece of foam that will let through all fine dirt particles. With these much finer filters the intake air will be musch cleaner. As a side effect, the air resistance is much lower (but I don't think this will be noticeable).

However, feel free to use my design if you have the same issue.

BTW: I think the thread is a 3/8" pipe thread, but I'm not sure. I just copied the outer diameter and pitch from the oroginal one and it fits.
